Rubrics allow for easier grading. The student will understand why they received the grade they did, as it will be based on the rubric.

List all expectations in the syllabus

Ensure keeping the students in mind throughout the design, development, and of course instruction.

Stay professional and maintain the same tone with your courses.

Engage each student individually 

Develop and maintain a professional relationship with all students. Leaving a video announcement would help as they would know who the instructor is, asides to just a name

I learned that keeping the students engaged will help them to retain the knowledge.
